PES Amazonian XL Mycelium box (2100 ML)



The PES Amazonian XL-MyceliumBox is an enhanced Mycelium box with 80% more substrate than the medium Pes Amazonian box. The Pes Amazonian is known to produce huge mushrooms and highly potent ones they are!

This XL-Mycelium Box contains the mycelium of the Psilocybe cubensis 'PES Amazonian' strain. The Pes Amazonian mycelium is colonized on a substrate of rye and perlite. The top layer of the substrate is covered with vermiculite as casing layer.

Our online manual for the mushroom mycelium box can be viewed at www.mushroomgrowbox.org.

Holding the double of the substrate, meaning the double of the expected PES Amazonian yield, the XL-MyceliumBox is an enhanced product allowing the formation of exceptionally big PES Amazonian magic mushrooms in an exceptional short amount of time.

Made for the amateur mycologist, the PES Amazonian XL-MyceliumBox highly reduces the probability of contamination and it's simplicity of processes will allow you to better focus on the amazing formation of mushrooms bodies. Made with the strongest redefined strains, growing mushrooms was never easier and more reliable.

If you do not want to start growing immediately after receiving the mushroom kits, the best place to store them is your refrigerator (not your freezer!). Do not store them longer than 2 months.

Additional Information

Step 1
Wash your hands thoroughly and clean the outside of the grow kit with a clean, damp cloth. Remove the lid, but keep it for step 3.

Step 2
Take a clean fork and make some holes in the top layer. Divide the holes regularly on the grow kit (6 to 8 rows of holes is enough). This allows the substance absorb the water better.

Step 3
Fill the kit with warm water up to the edge of the kit(20 º C). Place the lid and let the grow kit soak for 2 to 4 hours (Max 12 hours).

Step 4
After soaking, remove the lid of the grow kit and carefully pour off the water.

Step 5
Add warm water (20 º C) to the grow bag.
- For the 2100cc grow kit: 2 cups (0,5 liters)
- For the 1200cc grow kit: 2 cups (0.5 liters)
- For the 250cc grow kit: 1 cup (0.25 liters)
Put the grow kit in the grow bag. Make sure the water does not go over the edge of the grow kit.

Step 6
Close the growing bag by folding the top of the bag and secure it with two paperclips (part of the grow kit package).

Step 7
Put the grow kit in a place out of direct sunlight or under a lamp and not on or near a heater or heat source. The ideal temperature is between 20 and 25 º C. Make sure there is sufficient sunlight.

Step 8
Moisten the kit daily with a spray bottle. This is also important after harvesting.

Step 9
The first mushrooms will be visible in 10 to 12 days.

Step 10
The mushrooms should be harvested just before the skin underneath the hats starts to loosen up.
The harvest: grab the stem gently and turn the mushroom to the left and than to the right and gently pull. This way you can remove the mushroom as complete as possible. This way you can reuse the grow kit.

After harvesting, clean the surface of the grow and remove the old and dead mushrooms, so the new mushrooms have the ability to grow. Put the grow kit for the best results in the refrigerator overnight. Caution! Not colder than 2 ° C.

Start again from step 5 for the next harvest.

The ideal climate is 22 º C.
When you see the pinheads, put the kit overnight in a cool place, for example in a barn. The drop of temperature causes the mushrooms to get the idea that autumn is coming. Because of that, the mushrooms will grow faster so you can yield earlier.
